Limiting factors pertaining to air quality in Latah County include:

 

  • Agricultural Field Burning

  • Forest Slash Burning

  • Unpaved Roads

Management Objectives for Air Quality Limiting Factors

 Agricultural Field Burning 

  1. Avoid air pollution impacts to public health by managing agricultural field burning to minimize impacts to the public while maintaining profitable crop production.

 Forest Slash Burning 

  1. Avoid air pollution impacts to public health by managing forest slash burning to minimize impacts to the public while maintaining long-term forest health.​

 Unpaved Roads 

  1. Avoid air pollution impacts to public health by reducing particulate matter input from unpaved roads in, and within close proximity to, towns and unincorporated places.

  2. Reduce particulate matter inputs from high-traffic unpaved roads.
